Regional Notes

Red shoot appears as reddish discoloration of new growth on affected plants. This condition can result from viral infection or environmental stress. Monitor plants closely for symptom progression. Remove severely affected material. Manage vectors and maintain plant health. Monitor your plants closely and implement integrated management strategies. Prompt removal of infected material helps limit disease spread Early detection and prompt management of symptoms help limit disease spread.

Prevention works better than treatment for red shoot. Choose resistant varieties when they exist, site plants where air moves freely, and maintain good sanitation by removing debris and infected material. When chemical intervention is necessary, timing matters more than product: apply protectants before the infection window, not after symptoms appear.
